Run Time shared library problems

I’m trying to solve the issue of having a single large movieclip referenced across multiple flas to reduce load time for the final product.

Basically like an externally linked library or rsl in flash builder but for art assets in the flash ide in the library.

I started with runtime shared using the standard flash runtime shared library but found this did not work if I put an instance name on the runtime shared asset. Far as I can tell is because the runtime shared class is not yet loaded on frame one which is where externally linked classes are declared.

Anyways sorry if this wasn’t terribly clear. Please ask for clarification if it doesn’t make sense. Hope someone has some advice.

thx
